Unethical behavior by Gridhawk security services

Horrible security ever, they don’t respond to alarms and they just can’t get someone to assist you. I’ve been having a faulty system and I reported it but funny besought they always promise to send someone to come fix it, but no one comes. I’ve been trying to cancel their services but their sales team is always on a bathroom break and they always promise to get back to you. It’s been a month of trying to cancel with them but I can’t cause I never get the relevant person to help.
